Coaching vs. Consulting

As Instructional Coaches, a major part of our job is have "Constructivist Conversations" with teachers (coaching). In other words, in our conversations, we should not be telling teachers what they need to be doing but instead getting them to tell us what they need to do. This sounds so simple to do but it is very diffucult, especially for a person such as myself. I REALLY like to tell people what to do (just ask my husband!!). You have to be patient and practice appropriate questioning strategies to get people to think on their own. It is not easy. I am struggling in this area. I know that people who are able to come up with answers by themselves will more likely make changes. Why is this so hard to do? Why do we, as teachers, like telling rather than listening and letting others explore?
